  • R60ABD1 radar module is the use of 60G millimeter wave radar technology, detection of human skin subtle changes, through the algorithm to calculate the respiratory frequency, heartbeat frequency, motion amplitude, abnormal activity information.
  • Secondary development information: 1) Radar built-in algorithm processor, direct output results, no need for cloud computing 2) The detection results of radar are output by SCM serial protocol 3) Communication module (WiFi, 4G, etc.) is not included in the design of radar module.
  • Detection range: 1) Trigger range and accurate detection range of yunfan radar calibration 2) The maximum accurate detection range is usually within 40 degrees conical Angle within the design range of radar antenna.
  • 3) The radar detection range can be adjusted by adjusting the Angle and distance 4) The detection accuracy is closely related to the detection target distance.
  • Usage: 1) Installed in a fixed position, accurate detection of external moving objects 2) Radar penetrates low density objects such as thin wooden planks. Caution False positives are caused by large detection range 3) Due to different electromagnetic wave noise in different environments, electromagnetic environment at the bottom of radar is required in some cases.

  • (current greater than 100mA)，PWM signal receiving frequency range: 1KHZ-3KHZ.
  • When power on for the first time, it is best to do a calibration and debugging: find a signal with a 50% duty cycle and connect it to PWM and GND. Jumper caps set the corresponding voltage range. When the frequency is 1KHZ-3KHZ, use a multimeter to measure the two ports of VOUT and GND. At this time, the meter displays about 5V. Adjust the potentiometer on the board so that the multimeter displays 5.00v.003cbr003e.
